Abstract

1,114,659. Refrigerating; gas liquefaction apparatus. PHILIPS GLOEILAMPENFABRIEKEN N.V. 29 Nov., 1966 [2 Dec., 1965], No. 53327/66. Headings F4H and F4P. Refrigeration apparatus comprises two parallel fed expansion orifices, the input to one orifice being pre-cooled by gas from that orifice and the input to the other orifice being pre-cooled by gas from both orifices. As shown, a first tube 6 has a ribbed section wound around a cylinder 50 and is connected to an expansion orifice 8 inside a coupling piece 50 while a second tube has an unribbed section 5 wound around tube 6 and a ribbed section 5<SP>1</SP> wound around a further cylinder 51, the second tube being connected to an expansion orifice 14. Apertures, not shown, are provided in coupling 50 so that tube 6 and section 5 are both cooled by gas from orifice 8 while section 5<SP>1</SP> is cooled by gas from orifice 14. The above apparatus is housed in a vacuuminsulated tube (Fig. 3, not shown) which has an outlet for liquefied gas (nitrogen or argon), which is used to cool an infra-red analyser. The orifice 14 comprises an apertured disc 11 held on the end of a threaded cylinder by a sleeve 12. Cylinders 50, 51 are made of nylon, coupling 52 of silver and tubes 5, 6 of nickel, the ribbing being formed by square-section silver wire wound around the tubes. The tubes are fed in parallel via a porous copper filter 4. Nitrogen may be fed to tube 6 while hydrogen is fed to tube 5, 5<SP>1</SP>.
